3Play Media's format could do this. Their output is usually a transcript where you can click on any word and it will take you to that second of the video. The software they've developed for the people who create the captions does go second by second as well. I don't know if they've ever considered having that as a display option. They're just one of the only companies I can think of for whom it wouldn't involve a whole rethinking of how they create the captions.
